Just wondering if there is any news on adding a native inventory archiving feature to Spiceworks? I thought I heard something about this being a new feature to soon be released during Spiceworld 2015.....

Actually, we wrote an App Center app to handle this. It's ready for use, but hasn't been officially turned on (I think that will happen today). It is only compatible with 7.5, so you will need to upgrade if you're not currently running it. This will remove your devices from inventory and store them up in the cloud, so you can reference them if/when you need to.
